UnderHood2

What steps will reproduce the problem?
Issue 1: Mousing over any frame produces an error
Issue 2: Setting a raid target on a player or selecting a player that has a raid target produces inconsistent results. UH2 generally does not display the target's raid icon correctly.
Issue 2a: If I set a raid icon on myself then target another player, that player will appear to have the same icon I do.
Issue 2b: If I select a player that already has a raid icon, it doesn't properly show on my target frame. (I have confirmed that the raid icon is set to show for "target").
Issue 2c: If I reload UI after already having a raid icon on myself, it doesn't properly show on myself after the reload.

What is the expected output? What do you see instead?
Issue 1: Instead of the game providing tooltips whenever a frame is moused over, I get an error. (However, the frames can correctly be clicked on and used for targeting purposes.)
Issue 2: The addon does not seem to update correctly to show raid icons. It will show the icon the moment it is set on a target if I have them selected when the icon is placed (in other words, if I'm the one placing the icon on them, I'm able to see it) but when I select a target that already has an icon, it doesn't show (or it shows the icon that's set on me, if I have one). I haven't fully tested this issue, but my guess is that there's an issue where UH2 isn't dynamically updating certain frames.
Issue 2 continued: I think this same update issue may occur for in-combat icons and maybe others. I haven't tested or confirmed all yet. But I have noticed that my target frame tends not to show the combat icon consistently. (It only just now occurred to me that it may be related the issue described above.)

Issue 2: No. Although I suspect the error above may have something to do with Issue 2 (though I don't know enough about API to be certain).

Please provide any additional information below.
Not sure there's much else to say besides: Thank you for making such a great addon. I like working with UnderHood2. P.S. There was one other error I was getting before, but a player-produced "patch" seemed to have fixed it. The patch is shown on the Curse.com website on the UnderHood2 page.
